  •  Choice of triggering method is important.

 Check 

the manual for triggering options. 

BUMP ACTION TRIGGER

  •  When using the bump action trigger, be careful of 

unin tentional double fires resulting from tool recoil. 

Unwanted fasteners may be driven if the contact 

trip is allowed to accidentally re-contact the work 

surface. (Fig. T)

    TO AVOID DOUBLE FIRES:

  •  Do not engage the tool against the work 

surface with a strong force.

  •  Allow the tool to recoil fully after each 

actuation.

  • Use sequential action trigger.

  •  When “bump” actuating the framing nailer, 

always keep tool in control. 

Inaccurate placement 

of tool can result in misdirected discharge of a 

fastener.

SEQUENTIAL ACTION TRIGGER
    •   When using the sequential action trigger, do 

not actuate the tool unless the tool is placed 

firmly against the workpiece.

  •  Do not drive nails blindly into walls, floors 

or other work areas.

 Fasteners driven into live 

electrical wires, plumbing, or other types of 

obstructions can result in injury. (Fig. U)

  •  Stay alert, watch what you are doing and use 

common sense when operating a power tool. Do 

not use tool while tired or under the influence 

of drugs, alcohol, or medication. 

A moment of 

inattention while operating power tools may result 

in serious personal injury.

WARNING: 

Some dust created by power sanding, 

sawing, grinding, drilling, and other construction 

activities contains chemicals known to the State of 

California to cause cancer, birth defects or other 

reproductive harm. Some examples of these chemicals 

are:

•  lead from lead-based paints,
•   crystalline silica from bricks and cement and 

other masonry products, and

•   arsenic and chromium from chemically-treated 

lumber.

Your risk from these exposures varies, depending on 

how often you do this type of work.  To reduce your 

exposure to these chemicals: work in a well ventilated 

area, and work with approved safety equipment, such 

as those dust masks that are specially designed to filter 

out microscopic particles.

WARNING: ALWAYS 

use safety glasses. Everyday 

eyeglasses are NOT safety glasses. Also use face or 

dust mask if cutting operation is dusty. ALWAYS WEAR 

CERTIFIED SAFETY EQUIPMENT:

•  ANSI Z87.1 eye protection (CAN/CSA Z94.3),
•  ANSI S12.6 (S3.19) hearing protection,
•  NIOSH/OSHA/MSHA respiratory protection.

BEFORE OPERATING THIS TOOL, CAREFULLY READ 

AND UNDERSTAND ALL INSTRUCTIONS IN THE 

“IMPORTANT SAFETY INSTRUCTIONS” SECTION.

tool and remove fasteners from magazine before making 

adjustments or personal injury may result.

Trigger 

WARNING: 

Keep fingers AWAY from trigger when not 

driving fasteners to avoid accidental firing. Never carry 

tool with finger on trigger. In “Contact Bump Actuation 

Mode” tool will fire a fastener if safety is bumped while 

trigger is depressed.
In accordance with the ANSI Standard SNT-101-2002, 

the D

E

WALT Nailers are assembled with a sequential 

action trigger. For a replacement trigger contact your 

authorized service center or call (AUS) 1800 654 155 

or (NZ) 0800 339258.
The

 gray trigger

 with   imprinted on the side, (Cat.# 

D510023 kit) is the single sequential action trigger and 

causes the tool to operate in this mode.
The 

black trigger

 with 

 imprinted on the side, 

(Cat.# D510020 kit) is the bump action trigger and 

permits the tool to be actuated in this manner.
For defining the use of the 

sequential action trigger

 and

trigger assembly as shown.

  5. Push the rubber grommet (A) onto the end of the 

dowel rod.

Air Fitting

The D

E

WALT framing nailers have a standard 3/8” pipe 

thread for the air fitting. The tool is assembled with a 3/8” 

to 1/4

"

 adapter installed in the end cap.

TO INSTALL AN AIR FITTING 

  1. Wrap the male end of the fitting with teflon tape 

prior to assembly to eliminate air leaks.

 2. 

To install a 1/4

"

 fitting:

 screw the fitting into the 

3/8” to 1/4” adapter in the end cap of the tool and 

tighten firmly.

 3. 

To install a 3/8
